ACETYLENE-GAS PRODUCER.

Application filed September To all to/wm t may concern:

Be it known that I, FRITZ EIKENROTH, a citizen of Germany, residing at Heringen, Werra, in the Province of Cassel, Germany,

have invented certain new and useful Improvements in Acetylene-Gas Producers, ofy

which the following is a specific-ation.

This invention relates to acetylene gas producers, and the main object is to provide a device which automatically begins producing gas when `the pressure in the gasometer has been reduced to a predetermined point.

Another Objectis to provide a generator having a raised calcium carbide hopper which is normally closed and is opened when the pressure of the gas generated by the preceding portion of calcium falls to a predetermined level. f

These and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a sectional elevational view of the gas generator, showing the bell in lifted position.

Figure 2 is a sectional top plan view taken on line 2 2 of Figure 1.

Figure 3 is a sectional elevational viewv of the carbide hopper, showing the releasing gate in closed position.

Referring in detail to the drawing, the numeral 10 indicates the walls of a rectanguiar tub having a sloping bottom 11 at the lower end of which a tube 12 is embedded in the wall 10 and has a strap 13 secured thereto within the confines o-f the tub. An an-v nular plate 14 normally covers the inner open end of the. tube and has an'ear projecting therefrom pivotally secured to an angular lever 15 intermediate its length, the upper end of said lever being pivotally connected to the strap, and the lower end being similarly connected to a vertically slidable rod 16 which has a loop handle 17 at its upper end. The uppper interior edges of the tub walls are recessed to support a platform 18 which covers the tub. The latter is at all times filled with water to the level indicated in Figure 1.

At one end of the tub an inverted tank 19 is mounted in an opening formed in the platform 18 and is fixed in place by a flanged ring 20. The greater portion of the length of the tank which extends into the tank is immersed in the water, and the lower 24, 1923. seria No. 664,631.

open end has a door 21, the latter being secured to a vertical shaft 22 journalled in suitable brackets, said shaft having a handle 23 at its upper end by which the door 21VVV is manipulated. N ear the lower end of the tank an annular plate 24 is pivoted and has receptacles thereon adapted to receive the spent calcium carbide ashes. f Y

A hop-per 25 in which the calcium carbide is stored, is mounted above the tank and has a casing 26 therebeneath in which a funnel 27 is mounted, said funnel directly communicating with the hopper chamber above it. The mouth of the funnel 2'?"L may be opened or closed by a gate 28 slidable on angle irons 29, the latter being in slightly inclined position. An ear 30 is rigidily secured to the underside of said. gate and has one end of a connecting lever 31 secured thereto. Leve-rs 32 and 32a are fixed on a rotatable spindle 33 which passes thru the casing. One end of the lever 32 is secured to the connecting levers 31, both the levers 3l and 32 being in. the casing, the lever 32a being on the exterior side of the casing. The levers 32 and y32a function in the manner of a bell crank; AThe lower end of the casing 26 is flanged and has a4 tube 34 secured thereto, said tube having a plurality of stay rods 35 at its lower' end to which a conical baffle 36 is secured. Y The upper end of the hopper 25 has a flanged opening normally closed by a. flat plat/@which seals the hopper thru the medium. of a screw 37 which threadably engages a yoke 38.

A gasometer tank 39 has its lower end rigidly attached to the cover 18 and is provided with a concave bottom 4() at a position near its lower end. A flanged ring 41 is fixed to the upper end ofthe gasometer and has rods 42 rising vertically therefrom, the latter having their upper ends connected by a rod 43. A vertical ybar 44 having an inverted cup l45 iixed near-its upper end, is securedto rod 43 intermediate its length. Said rodextendsy downwardly into the .gasometer tank, its lower end being securely fixed to the bottom 40. A bracket 46 is attached to the upper wall of the gasometer tank 39 and has a normally vertical lever 47 pivoted thereto, the lower end of said lever being substantially circular in outline and being provided with a notch 48. An arm 49 projects from the circular end of the lever and is pivotally connected to the lever 32a on` the exterior of the casing, by a bar 50.

A bell 51 having plates 52,*andA 52 projecting from the top 53, is slidably mounted` irr the gasometer tank 39, the plates havingA holes therein which receive the guide rods 42. The plate 52si has an extension 54 vvliich engages the notch 48 at one position.

A pair of tubes and 56 rise vertically in the gasometer, the?` upper ends opening into the bell slightly above the upper edge or the" gasonieter, the' lower ends paissi'i'rg-r thru the bottom' 40 andbeingf their-bent air-T gularly outward to pass thruv the' g'asome'ter Wall. The lower end of the' tube 56 is' cou-pled to and opens into a relatively lsmall container 57. The latterv is directly' con# ne'cted to: the tank- 19 by piping 58. The lower end of the tube" alsohzrs af length orf piping an'd is providedpvvith a valve 59 and a nfilter 601, the latter having a tube 61v extending from its side to' which outlet pipes may te` attachee. The lap 5s of the' een is" deformed into a cup* 62, and a sleeve 65 which envelopes? the bar 44 is rigidly mounted in said cup', the upper end project: ing into the same, sal-id cup when in use be*- ing filled with Water. l The Operation or this' gas generator o'llo'v'vs. The tub and the gasometer are' lilled with vv'ater to the levels indicated in Figure 1.A In Fia-ure i", the level or the Water in the bell- 5'1is' shoyvir lovve'r than the Water in the' gasometer 39, which is caused by the pressure or the' gas in the upper cham-1 berv or the bell 51.v As the passes' outof the bell thru the tube 55 and `thence thru the container Where it is filtered by ab'- sorbent cotton and linie, to. the supply ut'- letl 61,'4 the bell 5'1 will be lovvered'.` As the bell gradually sinks to' its lovvestv positin,` the extension 54 or the plate 52al rides into the notch 48 of the lever 47 and rotates said lever' tothe positionindicated byl the' brble lines in Figure 1. The lever 47 in lrotating lifts the bar 50 which in turn rotates the levers 32 and 3W about the spindle 33.- This movement causes the `gate 28'- to be urged side'vvise thru the medium of the lever 31 and uncovers the funnel 27. When the latter is opened, calcium carbide' salts are pre# cipita-ted from the hopper 25' into the tube' 34 and fall into the tank 19'; Thev union of the vater and calcium carbide, (as lis vv'ell# known)y causes tlie release of acetylene' gas which passes' upvvardly into the upperI por# tion of the tank 19 and is prevented from entering the tube 34 by the conical baille' 36. The gas then passes thru the piping 58 and tube 5G into the chamber at the upper end of the bell 5l.y As thef'gas is released iiito the bell chamber, the bell rises, and in` so doing, the extension 5'4l rises and by contact-A ing with the adjacent surface' of lever 47, rotates the latter to4 vertical position, by which movement the gate- 28 is shifted over the open end 0In the funnel 27 ,thereby clos! ing the latter. VThe inverted cup 45 mounted concentricalfly on the bar 44 near its upper end is rigid and does not change its position When the bell 51 is elevated. As the gas in the upper rend of the bell chamber causes' thgekl-i'quid therein to be released, said liquid Will pass up thru the member 63 into member (52: As theY gas generated in the device lifts the bell 51, the cup 45 Will register in the flooded portion of member' 62 and seal the opening at the upper end of the sleeve' 63, thus stopping the liberation of.

gasfor Water thru this opening". The bell continues to rise the quantity of gas incre'ase's",-an`d`f, when' the valve 59' is closed, excess quantity or ,gas may` form in the bell.y This excess may bel liberated into the atmosphere thru the' slee've in the' ollo'vv infg manner. The pressure" of the gas vv'ill urge the water upvvar'd thri'r the sleeve 63 and Will o'iierilovv over' the topo'l? the bell into the gasom'eter, thus giving" the gas in the bell greatervolumetric dimension.- As' the'v pressure increase'coitiiuesi, additional Water Willfloiv from the' bell thru the sleeve 63 Will spilled over the vv'all of the gasometer. In this manner the@ vvate'r the belly ivi'll' be decreased until the lower end or the' sleeve 63 is uncovered, When the' eX- cess gas' vvill pass thru said tube' and be liberated into the gasometer and the exten? sioir 5'4 Wil-l again rotate the lever 47, which will open the' gate 28 to precipitate a new quantity or calcium carbide from which a'dditional gas will be generated. Thus it is apparenti that, with this deviceA additional calcium carbide is precipitated automaticallyv when the gas supply' has been lovvered to a predetermined level;
